Claims. 1

This invention relates to oil burners, the object being to provide a new and improved oil burner having a generator at the upper end to which the oil is discharged and a burner therebelow to which the vaporized oil passes and a vaporizingpan therebelow and means at the upper end of the generator to prevent rotation of the flame, the assembled parts providing a vertical passageway for the air and gas streams.

These and other objects and features of the invention are hereinafter more fully described and claimed and an'oil burner embodying my invention in its preferred form is shown in the accompanying drawing in which:

Fig. 1 is a plan view taken from the upper side of the burner. I

Fig. 2 is a vertical section taken on line 2-2 of Fig. 1.

My improved burner comprises a generator head I to which a valve controlled oil supply pipe 2 opens to the lower side by means of which oil is supplied thereto. On the opposite side of the head is an open ended vertical conduit 3 which is connected with the distributor 4 by means of an elbow 5. The distributor has a series of apertures 6 in the inner face thereof through which the oil vapor discharges inwardly. The generator I is supported on the upper end of a cylindrical casing I which has an inwardly extending flange Ia at the bottom providing a central opening to permit positioning the distributor 4. The several parts are supported on the legs 8 of which there are three. Each of the legs is provided with a flange 9 having a horizontal portion In supporting the starting pan II.

The pan has a central aperture having an upwardly extending flange I2 threaded to receive the conduit I3 which permits oil to pass through the pipe It to a waste conduit. The purpose of this arrangement of parts is to prevent oil from overflowing the upper surface of the pan. The oil is discharged directly to the chambered head I wherein it is subjected to the heat of the burner and the vaporized oil passes through the aperture 6 in the inner face of the distributor 4. Additional air to the burner is provided by spacing the burner from the flange Ia.

Centrally above the apertures is a spreader or deflector element I5 which tends to cause the gases to be mixed with air and pass through the central opening in the head. This spreader is supported by a vertical rod it having an eyed end IT by means of which it may be removed. At the upper end and resting on the upper curved Wall I8 of the generator chamber I are a series 2 of at least three plates I9, 20 and 21 which tend to prevent rotation of the stream of burning gases.

The chambered element I has a plurality of clean-out plugs 22, 23 and 24 by means of which any carbon accumulating in the chambered element I may be removed.

In operation the valve 2a in the supply line is opened to a desired degree and the oil flows into the chambered element I and, as the distributor 4 becomes heated by the burning oil in the generator pan I I, it discharges in gaseous form through the apertures 6 and passes upwardly through the central opening of the generator head I.

To start the burner the valve 2a is opened to allow oil to pass to the generator I and through the distributor 4 into the pan II which may be ignited in any approved manner. The flame of the burning oil in the pan II impinges directly upon the distributor 4 and the flame is deflected outwardly by means of the circular member I5 to contact the inner periphery of the casing 'I and contacts the bottom wall of the generator chamber I. The vaporized gas passes downwardly through the conduit 3 and thence through the apertures 6 in the generator 3 and passes in condition into the casing I and thence into the furnace chamber between the plates I9, 20 and 2| which prevent rotation of the flaming body of gases.

Variation in the intensity of flame is controlled by means of an inlet valve 2a in the supply conduit 2 which may be of any approved type and controlled in any approved manner to thereby vary the volume of flow of oil to the generator. The valve 2a may be of any approved type and its purpose is to vary the intensity of the flame to maintain a desired temperature in the space to be heated.

In operation of the burner a small quantity of oil is discharged into the generator pan I I and ignited to thereby heat the bottom wall. of .the generator head I and thus gasify the oil therein. Suction due to air flowing past the opening 6 and pressure of the vaporized oil causes gases to flow downwardly from the generator I and thence through the apertures 6 in the distributor 4 and thence upwardly in mixture with air to contact with the bottom and inner side wall of the cham her. The volume of flow of oil per unit of time is controlled by the valve 2a in the supply line 2.

It is believed obvious from the foregoing description in conjunction with the drawing that my improved oil burner is simple and inexpensive in construction and eificient in operation and that the various objects and features of the invention are attained by the structural relationship and form of the various parts.

Having thus briefly described my invention, its utility and mode of operation, what I claim and desire to secure by Letters Patent of the United States is:

1. In an oil burning apparatus, a burner head having a ring like vaporizing chamber at the upper end, a valve controlled oil supply conduit opening to said chamber, a casing providing a chamber below the vaporizing chamber, a distributor in the casing comprising a chambered element of ring like form, the inner wall of the distributor having a series of apertures, means providing for flow of oil to the distributor, and a spreader positioned centrally of the distributor tending to deflect the gases toward the wall of the casing.

2. Oil burning apparatus comprising a burner head having a ring like vaporizing chamber at the upper end, a valve controlled oil supply conduit opening to said head, a casing comprising a chamber therebelow, a distributor in the casing comprising a chambered element of ring like form providing a central opening, the inner wall of the distributor having a series of apertures therein, means for providing flow of oil to the distributor, and a deflector positioned centrally of the distributor directing the burning gases toviding for flow of oil to the distributor, a deflector positioned centrally of the distributor directing the burning gases toward the vaporizing chamber, a pan below the distributor, and means for supplying the desired quantity of oil to the pan to initially heat the burner head.

4. Oil burning apparatus comprising a burner head having a ring like vaporizing chamber at the upper end, a valve controlled oil supply conduit therefor, a casing providing a chamber below the burner head, a distributor in the casing comprising a chambered element of ring like form providing a central opening, the inner wall of the distributor having a series of apertures therein, means providing for flow of oil to the distributor, a flame spreader positioned centrally of the distributor and directing the flame toward the vaporizing chamber, and means for preventing rotation of the flaming gases as they pass upwardly from the burner.

5. Oil burning apparatus comprising a circular burner head of tubular form in cross section providing a central aperture, means for supplying oil to the burner head, a distributor of ring like form below the burner head providing a circular chamber the inner wall of which is provided with apertures, .a conduit leading from the burner head to the distributor, the head having a series of apertures in its peripheral wall, a removable plug in each aperture to permit cleaning of the head, a flame spreader positioned centrally within the burner and above the apertures therein whereby the flame is spread outwardly to contact the lower wall of the head, a generator pan below the burner, legs for supporting the burner and associated parts, and valve controlled means for supplying oil to the burner head.
